Installation, Operation, and Care of

4146 Chopper

SAVE THESE INSTRUCTIONS

GENERAL

The 4146 Chopper is equipped with a 5 HP motor that rotates the worm at 215 RPM. The 4146 is designed

to use a #32 size knife and plate. Knives and plates are included with the chopper.

The stainless steel or hot dipped tin feed pan on the 4146 is removable or can be tilted, so it can be easily

washed at the sink or in place. Dimensions on the feed pan are 49" long x 263/4" wide x 41/2" deep at the

front edge and 9" deep at the high back edge. A cast aluminum guard is permanently mounted to the sides

of the feed pan. An electrical interlock system requires both the bowl and feed pan be in place before the

machine can be turned on. The machine housing is stainless steel. This machine is a oor model with

16" legs being standard option and provides a 213/4" clearance between the oor and the lowest point on

the adjusting ring. Other leg lengths (181/2" or 21") are also available. Sausage stuffers for hog or sheep

casings are available accessories.

The chopper can grind 60 to 65 pounds of boneless beef per minute, rst cut, through a 1/8" plate. The

second cut grind rate is 45 to 50 pounds per minute through a 1/8" plate. Frozen meat must be tempered

to 26˚F or higher before grinding.

INSTALLATION

UNPACKING

The chopper was inspected before leaving the factory. The carrier assumes full responsibility for the safe

delivery upon acceptance of the shipment. Check for possible shipping damage immediately after receipt.

If the chopper is found to be damaged, complete the following steps;

1. Carrier must be notied within ve business days of receipt.

2. Carrier's local terminal must be notied immediately upon discovery (note time, date, and who was

spoken to), and follow up and conrm with written or electronic communication.

3. All original packing materials must be kept for inspection purposes.

4. The chopper cannot have been moved, installed, or modied.

5. Notify Hobart customer care at (800) 333-7447.

Remove the carton from around the machine. Remove the machine top cover. Unscrew and save the four

shipping bolts and lock washers – they are to be reused for attaching the legs to the machine.

Prior to installation, verify that the electrical service agrees with the specications on the machine data plate.

Open the separate package containing the four legs. Assemble the adjustable leg (used for leveling) at

the right rear corner when facing the rear of the machine for right–to-left operation. Assemble the non-

adjustable legs at the other three corners. Replace the machine top cover. Standard mounting of the

controls is on the right side of the chopper for right to left operation.

Use the spanner wrench to loosen the adjusting ring. Unscrew and remove the adjusting ring using both

hands. Remove and discard the retaining washer and rubber pad used at the front of the worm where the

knife and plate are to be installed.

The chopper must be thoroughly cleaned and sanitized after installation and before operation. Refer to

the Cleaning section.

ELECTRICAL CONNECTION

Electrical and grounding connections must comply with the applicable portion of

the National Electrical Code and/or other local electrical codes.

Disconnect the electrical power to the machine and follow lockout / tagout

procedures.

A 11/16" diameter hole for a 3/4" trade size conduit is located in the bottom panel. Remove access panel

from the back of the unit. Refer to the machine data plate and the wiring diagram located on the machine

for proper sizing of branch circuit. Upon completion, fasten the access panel in place with screws.

THREE PHASE MACHINES

Three phase machines must be connected so that the attachment drive runs counterclockwise when

facing the hub. To check the direction of rotation, turn the chopper on momentarily. If rotation is not correct,

DISCONNECT ELECTRICAL POWER SUPPLY and interchange any two of the incoming power supply

leads. Reconnect power to the chopper. Turn the chopper on momentarily to verify correct motor rotation.

SAFETY INTERLOCK

This chopper has an interlock system that makes it inoperative with either the feed pan lifted or removed, or

the bowl section of the cylinder removed. When either the feed pan or bowl is not in position, the plungers

break the electrical circuit making the chopper inoperative.

OPERATION

Do not operate without guard over feed opening. Do not put hands into feed opening.

Use feed stomper.

After cleaning, assemble chopper Cylinder, Bowl, Worm, Knife, Plate, Adjusting Ring, and Feed Pan as

discussed in cleaning. Place the Deector over the Adjusting Ring.

• To start the chopper, push the start button

• To stop the chopper, push the stop button

The neness of cut depends on the hole size of the chopper Plate. The Knife and Plate must be kept clean

and sharp for a ne cut. The tightness of the Adjusting Ring does not regulate neness of cut; therefore

only moderate tightness is recommended. The Adjusting Ring should be only hand-tight.

Cut the meat into chunks about the size of a st and place in the Feed Pan. Feed meat under the guard

and into the Feed Pan opening. The special high back on the Feed Pan permits the loading of large

quantities of meat without spilling. Use the Feed Stomper to dislodge over-sized pieces or to dislodge

meat which may become stuck in the Feed Pan opening or the Cylinder opening. It is not necessary to

force meat through the chopper.

When the product is run through the chopper a second time, more speed is attained by feeding small

quantities at a time. Allow the machine to feed at its own rate.

CLEANING

Disconnect the electrical power to the machine and follow lockout / tagout

procedures.

The chopper should be thoroughly cleaned at the

end of each day or any time it is not to be used for

an extended period of time.

A heavy duty right hand feed pan is available in either

tinned steel or stainless steel. The pan can be removed

for cleaning in the sink or merely tilted back for in

place cleaning. The tilt-back feature allows cleaning

or removal of the cylinder without removing the pan

from the machine. To tilt the Feed Pan, unlatch the

clamps on the front of the housing and lift the end of

the pan. Lift the pan rest to a vertical position (Fig. 3).

After the Feed Pan has been tilted or removed, pull

the deector straight up to remove it. Remove the bowl. Using the spanner wrench, loosen the Adjusting

Ring. Unscrew and remove the Adjusting Ring with both hands. Hook the spanner wrench around the

Worm stud and pull the Worm end out of the Cylinder. Remove the Knife and Plate and then the Worm.

Place the removed parts in a sink for cleaning.

Using the spanner wrench, loosen but do not remove the cylinder nuts. With one hand on bottom of cylinder

for support (it is heavy), turn the Cylinder clockwise and remove to a sink.

Thoroughly clean all removed parts in a sink using hot soapy water and sanitize them. The Feed Pan

can either be taken to the sink or washed in the tilted position. Wipe machine housing with a damp cloth.

Prior to reassembly, apply a light coating of tasteless mineral oil to the inside of the Cylinder, the threads

of the Cylinder and the Adjusting Ring, the Worm edges, the Knife and Plate and any other exposed (non-

plated) metal surfaces.

To reassemble the machine, rst install the cylinder by rotating it counterclockwise until the ears are under

the cylinder nuts. Tighten the cylinder nuts nger-tight.

Slide the Worm into the Cylinder and rotate it to engage the square shank with the attachment drive.

With the spanner wrench, tighten the cylinder nuts.

Do not over-tighten the cylinder nuts.

Install the Knife (cutting edges out) and the Plate. Screw the Adjusting Ring on hand-tight.

Install the bowl and deector.

Reassemble the Feed Pan or return it to its non-tilted position.

The Feed Stomper may be stored in the throat of the cylinder.

MAINTENANCE

Disconnect the electrical power to the machine and follow lockout / tagout

procedures.

LUBRICATION

The fan end bearing of the motor is grease lubricated and sealed for life of the machine. The front motor

bearing is lubricated from the transmission and will not need lubricating attention.

Occasionally check the transmission lubrication level. Make sure the machine has stopped and allow time

for oil to drain from the ll tube. Remove the plug button on top of the housing. Remove the dip stick and

wipe off the dip stick and check to the indicator line.

Annually, or when needed, contact Hobart Service for transmission lubrication maintenance.
